Avoiding Interference In Shaper-Cut Gears - January/February 1996

The article "Avoiding Interference In Shaper-Cut Gears" appeared in the January/February 1996 issue of Gear Technology.

SummaryIn the process of developing gear trains, it occasionally occurs that the tip of one gear will drag in the fillet of the mating gear. The first reaction may be to assume that the outside diameter of the gear is too large. This article is intended to show that although the gear dimensions follow AGMA guidelines, if the gear is cut with a shaper, the cutting process may not provide sufficient relief in the fillet area and be the cause of the interference.
